TYPEVJEI'IING-EIACHINE.

Application filed August 1. 1919.

To all whom may concern:

lle it known that l, (inonon A. Sn1n,citi- Zen oi the United liitates, and resident of llion, in the county of l'lcrkiiner and State of New York, have invented. certain new andv use'liul improvements in Typewriting- Machines, of which the following is a specilication.

My invention relates to typewriting niachines and more particularly to the line lock mechanism For such machines.

The objects 01 my invention, generally stated, are to provide an improved line loch mechanism which is not liable to be dainaged or broken. and which is oi'l'cctive in operation.

To the above and other ends which will hcreii'ial'ter appear my invention consists of the features oi .-onstruction, arrangements oi parts and combinations of devices set l'orth in the following descriptimi and partici'lhn-ly pointed out in the :ippeni'led claims. v

Iln the drawings, whercii'i like reference characters indicate corresponding parts in the different views,

l igure ii is an enlarged detail ,traginentary "front elevation with parts in section showing a portion of a line lock mechanism and some of the associated parts.

Fig. 2 is an enlarged detail irag'inentary bottom plan. view of the same.

Fig. l; is an enlarged detail liwrgnmntary slceletonized perspective view of the line lock. mechanism and some ot the associated parts.

The present invention is in the nature oi an improvement on the construction employed in the Nos. ill and. ll Reining-ton inachines. and on that disclosed in the patent to Berry No. 956,672, dated. i l lay 3, 19.1.0.

So tar as the present invention is con cerned it may be understood to be embodied in a No. l() or No. 11 Remington machine, though it may be embodied in other styles oi? machines.

The lacy levers l are each provided with an upwardly extending hook-like prcjection Specification of Letters Patent.

2, beneath the engaging face 3 of which a locking flange 4;, on a line locking member or bar 5, is adapted. to be shifted to limit or prevent a depression of each key lever, and thereby prevent a printing operation and an actuation oi. the carriage escapeinent as in the Remington machines. 7

The locking bar 5 ispivoted at 6 to the base of the machine and has a. forwardly extending arm 7 to which the lower end. of a depending two-part link 8 is i i.voted. The upper end oi the link is pivoted at 9 to an angular sheet metal lever 10, lulcruined at 11. to a post 12 on the top plate .13 ot the ma chine. The lever ll) is bifurcated at llto receive a depe'mling linger or flange 15 of a sheet metal slide, designated as a whole by the re'lereniiie numeral 16. This slide is mounted for longitudinal sliding movement on a fixed support, which in the present instance is the for ard fixed carriage rail 1.7 secured by screws 18 to the post 12, and to a corresponding post at the other side of the top plate. The slide is slotted at 19 to receive the stems oi shouldered, headed, screws 20, the threaded stem of each of which is received in a tapped opening in the under side of the rail 17. The rail has a longitudinal groove or cavity 21 cut in the under side thcreoi, thus forming a housing in which parts of the line lock n1echanisni are received, as will presently appear. It will be seen that the slide 16 covers the bottom or open mouth oi the cavity so that it is inclosed on all sides. A lug 22 is struck up from the body oi, the slide and extends into the cavity or housing. is. contractile spring 23 contained within the cavity or housing, being connected at one end to the leg 22 and at its opposite end to a pin 29lseated at one end in an opening 25 in the rail and projecting into the cavity 21 therein. The force of the spring is exerted to move the slide 16 to the right until the lefthand end walls oil the slots 19 contact with the screws 20.

A sheet metal. link or connecting member, designated as a whole by the reference numeral 2G, is pivoted on the slide by a shoul dered, headed, pivot pin 27 riveted to the slide. The left-hand end of the member 26 has an upwardly bent stop or finger 28 which extends up into an opening or slot 29 in the slide, and coacts with an end wall 30 thereof to limit the pivotal movement of the member 26 in one direction, or back to normal position. A lug 31 is struck up from the member 26 and projects upwardly through an opening or slot 32 in the slide and into the cavity 21. A contractile returning spring 83 is con-- tained in the cavity or housing, and is connected at one end to a lug 31, and at its oppositc end to a lug 84 struck up from the slide and extending into the cavity or housing. The force of this spring is exerted normally to maintain the connecting member in the position shown in Fig. 2, with the stop 28 bearing against the rear wall 30 of the slot in which. it is received. To the right of its pivot the member 26 is formed with a goose-neck or extension which terminates in a bifurcated or slotted portion 35 that embraces an extension '36 of a line lock actuator and stop,'desi'gnated as a whole by the reference numeral 37. This stop is mounted on a casting 38 secured to the front rail 1'? by screws 39. Cylindrical bearings are formed in the casting 38 to receive trunnions 40 and 41 on the stop 37 and by which the stop is mounted for sliding andfpivotal' movement. From an inspection of Fig. 3 it will be seen" that a portion 2 2 on the stop extends into slot or cut-out 4:3 in the can riage rail 17 and that the right-hand face oi the part 42 contacts with the right-hand wall 44 of the cut-out, whereas the left-hand face of the part 42 is adapted to coact with the left-hand wall d5 of the cutout, and thus limit the sliding movement of the line lock stop in opposite directions. However, the stop may be turned on its trunnions with the aid 01": a finger piece 46 wi hout displacing the part 4:2 from the cut-out in the rail. This pivotal movement or" the line lock stop is provided in order to clear the usual carriage-carried line loch stop at? and thereby enable'the operator to release the line loch in the usual Remington construction. .lt will be understood that when the line lock stop 37 receives a pivotal movement, or is rocked to release as just described, the connection between the stop and the member 26 will cause the latter to turn around its pivot .27 on the slide against the force of the spring 33, and without breaking the connection between the stop 37 and the slide which enables the two to move together in their sliding movements. When the stop 37 is released by the removal of the finger pressure of the operator, the spring exerts its force to turn the connecting member 26 back to normal position, and through said member to rock the stop-37 back to normal position. As the carriage moves from right to left,

i the ad ustable carria e-carried line lock sto l? coacts with an extension or contact lug 37 on the stop 37, and carries the latter along with the carriage. This motion of the stop 37 is transmitted through the connecting device QGto the slide 16, moving the lata ter against the power of its spring there by rocking the lever 10 and moving the locking bar toloclring position, When the carriage is returned to the right, the spring 23 returns the slide 16 to the right, carrying the stop 37 back with the slide. At this time the spring 33.1noves bodily with the slide, and does not enter into action except to hold the member 26 fixed relatively to the slide, and to hold the stop 37 against turning movement.

From the foregoing description it will be seen that the construction or the parts is such that they may be easily assembled; that the springs for returning the parts are housed and maintained protected from damage, or from being broken in handling the machine, and that the construction is strong and ethcient in use, and is not liable to stick and result in an ine'l'lective or faulty operation. 7
